After completing this tutorial you will find yourself at a moderate level of expertise in Data Communication and Computer Networking from where you can take yourself to next levels. As tutorialspoint computer networks connect to a different network through gateways, these gateways are usually hosts or end points of the network.

That is why it is also called repeater. There are always chances to loose personal information such as name, address, credit card number. A network of networks is called comphter internetwork, or simply the tutorialspoint computer networks. A computer network spanned inside a building and operated under single administrative system is tutorialspoint computer networks termed as Local Area Network LAN.

Apart from communication and source of information, internet also serves a medium for entertainment. Before you start proceeding with tutorialspoint computer networks tutorial, I’m making an assumption that you are already aware about basic computer concepts like what is keyboard, mouse, monitor, input, output, tutorialspoint computer networks memory and secondary memory etc.

Let us explore some of these devices in greater detail. Therefore, one should be very careful while sharing such information. To inter-connect various continents, fibers are laid under sea known to us as submarine communication cable. At huge level, internet works on Client-Server model.

DCN – Computer Network Types

Network card is a necessary component of a computer without which a computer cannot be connected over tutroialspoint network. Motherboard has a slot for internal network card where it is tutorialspoint computer networks be inserted. One should use credit cards only through tutorialspoint computer networks sites. Internal and External Network Cards. Ethernet is a technology that defines protocols for establishing a LAN.

Network cables are required to provide network access. Wi-Fi technology is used to achieve wireless connection to any network. As the name suggests,the Wide Area Network WAN covers a wide area which may span across provinces and even a whole country. PAN has connectivity range tutorialspoint computer networks to 10 meters. This helps in maintaining network speed even during high traffic.

A router is a network layer hardware device that tutorialspoont data from one LAN to another if both networks support the same set of protocols. RJ45 tutorialspoint computer networks the acronym for Registered Jack Through the networking system, it is very simple to decentralize the data processing system.

Basics of Computer Science – Networking

Connect a printer, scanner, or a fax machine tutorialspoint computer networks one computer tutorialspoint computer networks the network and let other computers of the network use the machines available over the network.

Before forwarding, the packets are checked for collision and other network errors. Wi-Fi is the acronym for wireless fidelity. Now-a-days router comes in wireless gutorialspoint using which computers can be connected without any physical cable. Networking networos has revolutionized the world and created a new arena for the overall development of every nation.

Computer Networking

A router is a type of device which acts as the central point among computers and other devices that are a part of the network. IP Address is a unique set of numbers such as External network cards are of two types: When a user requests a page using some web browser located on some Web Server anywhere in the world, the Web Server responds with the tutorialspoint computer networks HTML page.

Gateway uses packet switching technique to transmit data from one network to another. Such virus attacks may cause your system to crash or your important data may get deleted. LAN uses either Ethernet or Token-ring technology.

Modern devices come with their in-built wireless network adapter. Tutorialspoint computer networks Area Tutorialspoint computer networks or simply LAN is the technique of interconnecting a few computers located in a given premise.

Most branded computers have network card pre-installed.

It receives its data in the form of packetswhich are data frames with their destination address added.
